That screen—likely produced by LG—cost a disproportionate $28.50 per unit, according to iSuppli. The A4 processor—from Samsung, and the same as in the iPad—cost $10.75, and the new gyroscope chip came in at an estimated cost of $2.60.

It's not clear how much profit Apple's clearing with each unit—iSuppli doesn't take into account the marketing, design, manufacturing, etc. costs, or how much AT&T contributes—but it's safe to say it's at least in line with previous models. [Businessweek]
